Disclosed are systems, devices and methods for laser microporation for rejuvenation of tissue of the eye, for example, regarding aging of connective tissue and rejuvenation of connective tissue by scleral rejuvenation. The systems, devices and methods disclosed herein restore physiological functions of the eye including restoring physiological accommodation or physiological pseudo-accommodation through natural physiological and biomechanical phenomena associated with natural accommodation of the eye. In some embodiments, the laser system may be configured to treat ocular tissue off axis or in a region of the eye which is distinct from the visual axis or directed away from the pupil of the eye where the gaze of the eye is.

Methods and apparatus are configures to measure an eye without contacting the eye with a patient interface, and these measurements are used to determine alignment and placement of the incisions when the patient interface contacts the eye. The pre-contact locations of one or more structures of the eye can be used to determine corresponding post-contact locations of the one or more optical structures of the eye when the patient interface has contacted the eye, such that the laser incisions are placed at locations that promote normal vision of the eye. The incisions are positioned in relation to the pre-contact optical structures of the eye, such as an astigmatic treatment axis, nodal points of the eye, and visual axis of the eye.

A treatment method and apparatus for surgical correction of defective-eyesight in an eye of a patient, wherein a laser device is controlled by a control device, said laser device separating corneal tissue by irradiation of laser radiation to isolate a volume located within a cornea, wherein the control device controls the laser device to focus the laser radiation, by providing target points located within the cornea, into the cornea, wherein the control device, when providing the target points, allows for focus position errors which lead to a deviation between the predetermined position and the actual position of the target points when focusing the laser radiation, by pre-offsets depending on the positions of the respective target points to compensate for said focus position errors.

Further, the invention relates to a control device (18), to a treatment apparatus (10), to a computer program as well as to a computer-readable medium.

Generation of treatment recommendations for topographic-based excimer laser surgical procedures is described that includes generating accurate cylinder compensation and spherical compensation values that are adjusted to compensate for unique characteristics of advanced topographic-based excimer laser surgical systems. Generating treatment recommendations generally includes determining a topographic vector from a topographic corneal map of the eye, determining a posterior astigmatism vector and an anterior astigmatism vector for the eye, and generating an interior astigmatism vector using the topographic vector, the posterior astigmatism vector, the anterior astigmatism vector, and a manifest astigmatism vector. In various embodiments, the cylinder compensation is generated using the interior astigmatism vector and the posterior astigmatism vector, and the spherical compensation is generated using an initial spherical compensation modified by a topographic addback modifier and a cylinder addback modifier.
